Final answer:
Dexter rode an estimated 1.3 miles altogether after traveling 9/10 miles to the store and then 4/10 miles to his uncle's house.
Explanation:
You are asking how far Dexter rode his bike altogether after he traveled 9/10 miles from his house to the store and then 4/10 miles to his uncle's house. To estimate the total distance Dexter rode, we need to add the two distances together.
The sum of 9/10 miles and 4/10 miles is:
9/10 miles + 4/10 miles = 13/10 miles
To make it easier to understand, 13/10 miles can be converted to 1 3/10 miles, which is the same as 1.3 miles as an estimate, considering 10/10 equals 1 full mile. Therefore, Dexter rode an estimated 1.3 miles altogether.
The theoretical probability of choosing a red grape from a
bag of grapes is 2/9. There are 8 red grapes in the bag. How
many grapes are in the bag?
Answer:36
Step-by-step explanation: if 2 out of 9 or red and there are 8 red that means that divide 8 by to get 4 * 9 + 36
By using the theoretical probability formula, the total number of grapes in the bag is 36
ProbabilityFrom the question, we are to determine how many grapes are in the bag
Let the total number of grapes in the bag be x
From the probability formula,
[tex]P(A) = \frac{Number\ of\ favorable \ outcomes \ to \ A }{Total\ number\ of\ possible\ outcomes}[/tex]
Let R represent red grapes,
Then,
[tex]P(R) = \frac{Number\ of\ favorable \ outcomes \ to \ R }{Total\ number\ of\ possible\ outcomes}[/tex]
From the given information,
P(R) = 2/9
Number of favorable outcomes to R = 8
Therefore,
[tex]\frac{2}{9} = \frac{8}{x}[/tex]
2x = 9 × 8
2x = 72
x = 72 / 2
x = 36
Hence, the total number of grapes in the bag is 36.

Is d(10 + 20) equivalent to d x 10 + 20 X d?
Use a property, or properties, to explain. Please help : ‘ 0
Pleas do step by step!!! If you can’t that’s fine but if you’d like to p l e a s e
Answer:
Yes, it is.
Step-by-step explanation:
d(10 + 20) is equivalent to d * 10 + 20 * d. This can be proved with the distributive property, which states that a(b + c) = ab + ac.
Using the distributive property of multiplication over addition and the commutative property of multiplication, it is proven that d(10 + 20) is equivalent to d × 10 + 20 × d.
The question asks if the expression d(10 + 20) is equivalent to d × 10 + 20 × d, using properties of mathematics to explain.
First, let's simplify the expressions using the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. Applying this property, d(10 + 20) becomes d × 10 + d × 20.
Comparing d × 10 + d × 20 with d × 10 + 20 × d, we see they are indeed the same because multiplication is commutative—meaning the order of the operands does not change the result. Therefore, d(10 + 20) is equivalent to d × 10 + 20 × d.

The sum of two numbers is 39. The smaller number is 11 less than the larger number. What are the numbers
Answer:
14 and 25
Step-by-step explanation:
x = smaller number
y = larger number
x + y = 39
x = y - 11
now we sub
y - 11 + y = 39
2y - 11 = 39
2y = 39 + 11
2y = 50
y = 50/2
y = 25 <=== larger number
x = y - 11
x = 25 - 11
x = 14 <==== smaller number
The problem can be solved by setting up and solving two algebraic equations. The two numbers in question are 25 and 14.
Explanation:The subject of this problem is algebra. To solve it, we can set up two equations based on the problem's statements, and then solve those equations.
First, we know that the sum of two numbers is 39, so we can write that as: x + y = 39 (Equation 1).
Second, we know that the smaller number is 11 less than the larger number. Assuming x is the larger number and y is the smaller one, we can write this as: y = x - 11 (Equation 2).
To solve these equations in parallel, insert Equation 2 into Equation 1, that results in: x + (x - 11) = 39. Solving this equation simplifies to 2x = 50, so x = 25. Substitute x = 25 in Equation 2, we get: y = 25 - 11 = 14. So, the two numbers are 25 and 14.

on a 45-45-90 angle and the hypotenuse is 2 square root of 14 what is x and y?
Final answer:
In a 45-45-90 triangle, with a hypotenuse of 2√14, both legs x and y are equal and their lengths can be found by dividing the hypotenuse by √2, which results in lengths of √14 for each leg.
Explanation:
In a 45-45-90 triangle, also known as an isosceles right triangle, the legs are of equal length and the hypotenuse is √2 times the length of one leg. If the hypotenuse is given as 2√14, we can use the fact that the hypotenuse is √2 times the length of a leg to find the length of the legs x and y.
Let x represent the length of one leg and y represent the length of the other leg. Since the triangle's legs are equal in this special triangle, x = y. The relationship between the legs and the hypotenuse in a 45-45-90 triangle can be expressed using the Pythagorean Theorem:
x² + y² = hypotenuse²
Solving for x and y, we get:
x = y = hypotenuse/√2 = (2√14)/√2 = √14
Therefore, in a 45-45-90 triangle with a hypotenuse of 2√14, both x and y, which are the lengths of the legs, are √14.
What is the solution to this polynomial equation? x3 + 2x2 - 4x - 8 = 0
Final answer:
The solution to the polynomial equation x³ + 2x² - 4x - 8 = 0 can be found by factoring, which yields the solutions x = -2 and x = 2.
Explanation:
The solution to the polynomial equation x³ + 2x² - 4x - 8 = 0 can be found by factoring, using synthetic division, or by using numerical methods such as graphing or using a calculator. Let's use factoring to find the solution.
We can begin by factoring out the greatest common factor, which is 1:
x³ + 2x² - 4x - 8 = (x + 2)(x² - 4)
We can further factor the quadratic term using the difference of squares:
(x + 2)(x + 2)(x - 2) = 0
So, the solutions to the equation are x = -2 and x = 2.

Step-by-step explanation:
A and B are independent events.
P(A) = 0.40
P(B) = 0.30
what is P(A|B)?
Answer: P(A|B) = 0.40.
Step-by-step explanation: Since A and B are independent events, P(A|B) = P(A).
Therefore, P(A|B) = 0.40.
The probability of A given B is 0.40.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Since A and B are independent events, we know that:
P(A and B) = P(A) x P(B)
But since they are independent, we also know that:
P(A and B)
= P(A) x P(B|A)
= P(B) x P(A|B)
Thus:
P(A|B) = (P(A) x P(B|A)) / P(B)
We are given that P(A) = 0.40 and P(B) = 0.30.
We don't know P(B|A), but since A and B are independent, we know that:
P(B|A) = P(B)
So,
P(A|B) = (0.40 x 0.30) / 0.30 = 0.40
Thus,
The probability of A given B is 0.40.

For every 1 cup of red paint, [tex]\frac{4}{10}[/tex] cup of blue paint is needed
For every 4 cups of red paint, [tex]\frac{16}{10}[/tex] cups of blue paint are needed
Solution:
Given that, there are 3 1/3 red cups of paint for every 1 1/3 cups of blue paint
Therefore, ratio is
[tex]Red : blue = 3\frac{1}{3} : 1\frac{1}{3}\\\\Red : blue = \frac{10}{3} : \frac{4}{3}[/tex]
For every 1 cup of blue paint, ___ cups of red paint are neededLet "x" be the cups of red paint needed
Then we get,
[tex]\frac{10}{3} : \frac{4}{3}\\\\x : 1[/tex]
This forms a proportion
[tex]1 \times \frac{10}{3} = \frac{4}{3} \times x\\\\x = \frac{10}{4}[/tex]
Therefore, 10/4 cups of red are needed for 1 cup of blue
For every 1 cup of red paint, ___ cup of blue paint is neededLet "x" be the cups of blue paint needed
Then, we get
[tex]\frac{10}{3} : \frac{4}{3}\\\\1 : x[/tex]
This forms a proportion
[tex]\frac{10}{3} \times x = \frac{4}{3} \times 1\\\\x = \frac{4}{10}[/tex]
Thus, 4/10 cups of blue are needed for 1 cup of red paint
For every 4 cups of red paint,___ cups of blue paint are neededLet "x" be the cups of blue paint needed
Then, we get
[tex]\frac{10}{3} : \frac{4}{3}\\\\4 : x[/tex]
This forms a proportion
[tex]\frac{10}{3} \times x = \frac{4}{3} \times 4\\\\x = \frac{16}{10}[/tex]
Thus 16/10 cups of blue paint are needed for every 4 cups of red paint
The ratio of red paint to blue paint is 5:2. Therefore, for every 1 cup of blue paint, 2.5 cups of red paint are needed, for every 1 cup of red paint, 0.4 cup of blue paint is needed and for every 4 cups of red paint, 1.6 cups of blue paint are needed.
Explanation:The initial statement tells us that the ratio of red paint to blue paint needed is 3 1/3:1 1/3. Converting these mixed numbers into improper fractions, that ratio transforms to 10/3:4/3, which simplifies further to 5:2.
